3 hours ago · In the realm of algorithm challenges, the Contains Duplicate problem on Leetcode is a classic that tests your ability to handle arrays and detect duplicates efficiently. The problem statement is straightforward: Given an integer array nums, return true if any value appears at least twice in the array, and return false if every element is distinct.
1 day ago · In this quick tutorial, we have discussed 5 different approaches to remove duplicates from array, of which 2 are specific to Javascript language. In Approach 1, we sorted the array and used O (N) extra space. In Approach 2, we sorted the array but we used only O (1) extra space. In Approach 3, we used Set data structure, and used O (N) extra space.
5 days ago · Two pointers is really an easy and effective technique which is typically used for searching pairs in a sorted array.Given a sorted array A (sorted in ascending order), having N integers, find if there exists any pair of elements (A[i], A[j]) such that their sum is equal to X. Naive solution:[GFGTABS] JavaScript // Naive solution to find if there i
2 days ago · Given an integer array nums sorted in non-decreasing order, remove the duplicates in-place such that each unique element appears only once. The relative order of the elements should be kept the same. Then return the number of unique elements in nums.
5 days ago · Given an Array, derive a sequence of elements in which all duplicates are removed. There are basically three approaches seen here: Put the elements into a hash table which does not allow duplicates. The complexity is O (n) on average, and O (n2) worst case.
5 days ago · Given two arrays a[] and b[] of size n and m respectively, the task is to find the union of the two arrays. The input arrays may contain duplicates and our task is to return only distinct elements in the union. The union of two array is the array of all distinct elements that are in either array. We are allowed to return elements in any order. Exam
